JBJ Reaction HOB Power Filter

The JBJ Reaction HOB Power Filter delivers three-stage filtration in a compact hang-on-back design for freshwater or saltwater aquariums. Choose the model that matches your aquarium capacity and desired flow rate.

Key Benefits

• Three-stage filtration: Fine and coarse sponges capture debris, ceramic rings support biological filtration, and activated carbon provides chemical filtration.
• Dual intake design: A coarse sponge prefilter helps protect small fish and shrimp while a surface skimmer removes oily film and floating debris.
• Adjustable waterfall flow: Promotes circulation and oxygen exchange while allowing the output to be adjusted for the aquarium.
• Compact HOB installation: Hangs on the back of the aquarium to preserve interior aquascaping space.
